Storage lifespans: don’t confuse technology with data–Search Storage Blog by Randy Kerns

Clarification is needed about what lifespan means regarding storage because confusion is created by the way product messaging refers to both in the same context.

Lifespans of storage systems refer to many things: wear-out mechanisms for devices, technology obsolescence in the face of new developments, inadequacies of dealing with changing demands for performance and capacity, and physical issues such as space and power.

The wear-out mechanisms are tied to support costs, which typically increase dramatically after the warranty period that could run three years to five years in enterprise storage systems. These issues all lead to a cycle of planned replacement of storage systems, often triggered by the depreciation schedule for the asset.

For the information or data stored on a storage system, the lifespan depends on the characteristics and policies of that data. Information subject to regulatory compliance usually has a defined lifespan or period of time it must be retained. Other data may have business governance about retention. Most of the data is not so clearly defined, and is left to the owners of the data (business owners in many discussions) deciding about the disposition. Typically, data is retained for a long time – perhaps decades or even forever.
